The converters will automatically re-establish
link when connected to two 10/100 auto-
negotiating switches if link is lost. With other
manufacturers’ converters the user must
intervene to re-establish link.

ADVANCED PRODUCT FEATURES
Automatically detects and configures the twisted pair port on the converter to the
correct MDI or MDI-X configuration.
AutoCross™
If someone tells you media conversion is a
commodity product that anyone can bring
to market, they probably haven't looked at
the extensive product suite offered by
Transition Networks. With the industry's
most comprehensive offering of full-
featured products, Transition's media
converters stand out as "the choice" among
industry IT professionals.
Generally, media converters are low-level
OSI model devices with no IP or MAC
addresses and therefore are transparent to
the network. This "transparency" makes
them very inexpensive and easy to use, but
also can make troubleshooting the network
very difficult. In an effort to overcome this
difficulty and to make media converters
"visible" to network managers, Transition
has designed their full-featured products to
include the most advanced features on the
market today.
Eliminates an entire category of troubleshooting
No need to identify cable type—straight-through or crossover
No user intervention required to determine correct button / switch settings
Auto-Negotiation allows devices to perform automatic configuration to achieve the best
possible mode of operation over a link. Devices with this feature will broadcast their
speed (10Mbps, 100Mbps, etc.) and duplex (half/full) capabilities to other devices and
negotiate the best mode of operation between the two devices.
While the inclusion of this feature is beneficial, the ability to disable it is equally
beneficial. In the event of a non-negotiating end device trying to connect to a
negotiating device, the mode of operation will drop to the least common denominator
between the two devices (i.e. 100Mbps, half-duplex). Disabling this feature gives the
user the ability to force the connection to the best mode of operation when trying to
link with a non-negotiating device. Most Transition converters with Auto-Negotiation
will allow you to disable this feature.
Auto-Negotiation (802.3u)
Optimal link established automatically
Quick and easy installation
No user intervention required to determine best mode of operation
Link Pass Through is a troubleshooting feature that allows the media converter to
monitor both the fiber and copper RX ports for loss of signal. In the event of a loss of
RX signal on one media port, the converter will automatically disable the TX signal of
the other media port, thus "passing through" the link loss.
(see diagram below)
Link Pass Through
End device automatically notified of link loss
Prevents loss of valuable data unknowingly transmitted over invalid link

ADVANCED PRODUCT FEATURES
Far End Fault (FEF) is a troubleshooting feature that is generally used in conjunction
with Link Pass Through to notify both end devices of a loss of link. In the event of a
loss of the fiber RX signal on the far end converter the converter will automatically
generate a Far End Fault signal and send it on its TX fiber port to notify the near end
converter of a fiber link loss. Link Pass Through will then disable the copper links on
both ends; alerting both end devices of network trouble (see diagram below).
Transition Networks’s media converters that include the FEF feature do not need to be
used as pictured above as they will work with other network devices that support Far
End Fault per IEEE standards.
Far End Fault (802.3u)
Both end devices automatically notified of link loss
Prevents loss of valuable data unknowingly transmitted over invalid link
Allows for quick diagnosis and resolution of network problems
Transition Networks's converters will automatically re-establish link in all network
conditions.
Transition Networks's converters will automatically re-establish link when connected to
switches if link was lost. With other manufacturers' converters the user must reset the
converter to re-establish the link.
Automatic Link Restoration allows the users to continue using Auto-Negotiation with
Link Loss Notification features. With other manufacturers' converters the user must
disable Auto-Negotiation and hard set the link.
Automatic Link Restoration on Transition Networks's products allows users to continue
using Link Loss Notification feature activated in both directions. Many competitive
solutions allow for Link Loss Notification activation only in one direction. If Link Loss
feature is activated in both directions, competitive products are put in a "deadly
embrace" and they cannot restore the link without resetting the converters.
No need to reset devices
Auto-Negotiation Enabled
Link Pass Through Activated in both directions
PAUSE signaling is an IEEE feature that
temporarily suspends data transmission
between two devices in the event that
one of the devices becomes
overwhelmed. In the event that a device
needs some time to clear network
congestion, it will send out a PAUSE
signal to the other end device, which
will then wait a pre-determined amount
of time before re-transmitting the data.
Transition's converters will pass PAUSE
signaling unhindered; ensuring that the
message is delivered to the end device.
PAUSE signaling is not standardized
over fiber media. Transition's media
converters will communicate this
signaling over fiber between the
converters to pass this signaling on to
the other end device.
Pause (IEEE 802.3xy)
PAUSE enabled devices allowed to
work properly
Prevents loss of valuable data
transmission
Reduces bottlenecks and allows
for efficient use of network devices
Automatic Link Restoration
Single fiber technology offers a 50%
savings in fiber utilization. It is an
attractive solution to maximize the
usage of a limited number of fiber runs.
In a traditional optical link, a fiber pair
consists of two uni-directional strands.
The single fiber technology multiplexes
two optical wavelengths of 1310nm and
1550nm into a single strand fiber. In a
single fiber media converter each
wavelength is responsible for either the
transmit or receive function.
Consequently, the bi-directional
transmission is achieved by using a
single strand. The converters in a single
fiber scenario "match" each other's
wavelengths. Converter A transmits at
the wavelength of 1310nm and receives
at 1550nm while the other converter
transmits at 1550nm and receives at
1310nm. Therefore, converters are
usually used in pairs.
Single Fiber
Single fiber technology is available on
all Transition Networks Media
Converters in maximum distance ranges
from 20 to 80km.
